FRP Pipes

FRP pipes as new piping material for wastewater and water systems

FRP pipes

GRP and FRP composite materials are used as a pipe material in the industrial world since 1950. It was first used for wastewater plants in 1960. GRP composites are including use of fiberglass as the reinforcement and various resins as the matrix. Manufacturers of FRP pipes in India are using reinforced fiber which is long lasting and durable.

Fiberglass material is the modern glass fiber invented in 1938. It is kept molten in a large vat and drawn via dyes to create fibers. These created fibers are then bundled into rovings by professionals. The fiberglass produced at the end is used as reinforcement in plastic products.

Resin material (GRP) is classified into following types-

  • Polyester – it is one of the oldest and most common resins. Polyester is economical and offer great long term corrosion resistance.
  • Vinyl ester – it is a hybrid resin introduced by Dow Chemicals in 1970. This is the enhanced resin features chemical and heat resistance. This material is usually applied in industrial chemical industry for strong acids and oxidizing chemicals.
  • Epoxy resins – it was first developed in 1936. Epoxy resins are known for their high strength applications. These materials are also applied in projects where curing under water is needed.

GRP and FRP pipe durability records for sewage plants

Manufacturers from around the world conducted special test series in which they studied GRP pipes. The results have yielded a heavy database that not only reveal the performance of the product, but also allows extrapolation beyond a time-scale prior attempted. In the reports, they recorded that even after 150 years of service the pipes would maintain higher safety margin as compared to other applications.

In the samples, they include a variety of pipe designs, stiffness classes, diameters, and pipe materials from different facilities. These samples were tested by the team as per the ASTM D3681, subjecting the samples to bending load, putting tensile strain in the pipe invert when it is exposed to 5% concentration of sulphuric acid to stimulate the conditions in aggressive sewage.

Advantages of GRP/ FRP pipe systems –

  • Long lifespan and corrosion resistance to sulfuric acid and sulfide
  • Multiple jointing methods can be used – rubber seal couplings, flanges, permanent joints.
  • Light weight
  • Smooth internal surface
  • Economical
  • Speedy installation

What Happens When You Overlook FRP Pipes Made in India?

Fiberglass reinforced plastic material is sturdy and the products made of FRP materials required minimum attention. Manufacturers of FRP pipes in India always suggest their clients to never overlook FRP products even if they needed minimum care and maintenance. Composite FRP products maybe strong and durable, but their life depends on the way you care and sustain them. These are best feasible products that can replace old traditional pipes. Engineers leveraging FRP pipes should have proper understanding of its nature and properties.


There are many reasons behind the increasing demand of FRP range of products, we will explain them now.

FRP pipes are inherently corrosion resistant because of the inert nature of materials used for fabricating them as compared to general steel and cast iron. FRP materials have potential to resist corrosion from wide range of chemicals and fluids. Moreover, engineers can rely on an apt interior-liner or barrier material and make use of resin matrices so that pipe can accommodate internal and external corrosive environments that are not alike to each other.

Their light weight built is also a major benefit. General FRP pipe’s weight is about 25% of the comparable steel pipe and 10% that of comparable concrete pipe. This feature makes the product very cost effective as the cost of shipping, installation and handling is much lower.

These products are used by different industries, for example, oil fields mostly rely on light-weight FRP pipes to lower the energy needs related to drilling, pumping and offshore-platform operations. The fatigue endurance and the strength-to-weight ratio of fiberglass reinforced pipe are major attributes connected with replacement costs and the potential to intend high-performing, lightweight pipe systems.

A general FRP pipe doesn’t conduct electricity, and has better electrical properties as compared to steel pipes. FRP pipe can be fabricated as per the custom specifications. It means a customer can request for FRP pipe and give his own design to the manufacturer and avail the exact product at reasonable rates. Manufacturers design and intend complex shapes of FRP products and clients can avail these all products from them easily. Many of these shapes are not easy to fabricate and way too expensive when it comes to metallic materials.

Major characteristics are-

  • Corrosion resistance
  • Strength to weight ratio
  • Fatigue endurance
  • Lightweight construction
  • Dimensional stability
  • Electrical conductivity
  • Low maintenance cost
  • Intricate shapes
